And this is true; albeit maybe a little ‘opaque’ for new traders, or even experienced traders that haven’t yet found the study of price action. The study of price action entails reading past prices, to build an approach or plan for the future.
Surely, most traders that end up ‘making it’ as a trader will find this specific study of technical analysis eventually; but it’s usually only after multiple disappointments and failed attempts at building indicator-based strategies that zig when the market actually ‘zags.’ So, please allow me to elaborate on my earlier statement.

Price action will never lie to us, as traders, because it never purports to tell us what WILL happen; but rather it only tells us what HAS happened.”
